As you can see it’s heavily inspired by the excellent mixtape site Muxtape, and although they look very similar, the difference is major. On TapeCloud you can only add tracks from artists that has shared their music on SoundCloud and not upload own songs. So, basically it’s a very niched variant of Muxtape but might still be of some value for fans that like exploring music on SoundCloud and also for developers looking for examples of how to build audio/web-mashups.
